The explosions around the world in mobile phone use make some health professional worried.Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones.In England，there has been a serious debate about this issue.Mobile phone companies are worried about the negative publicity of such ideas.They say that there is no proof that mobile phones are bad for your health.
